Gastric dilatation (GD) and heartworm disease (HW) can significantly impact cardiovascular function, necessitating timely intervention. This study evaluated hemodynamic changes in these conditions using impedance cardiography (ICG), a non-invasive technique for real-time monitoring.
Cardiac parameters were measured using ICG in healthy controls, HW, and GD groups at baseline, during intervention, and post-treatment. Statistical analyses involved repeated measures ANOVA with post hoc comparisons, and relative changes (%) quantified hemodynamic improvements.
A significant increase in cardiac index (CI) occurred post-treatment in both HW (+14.71%, = 0.0102) and GD (+28.53%, = 0.0336) groups. Cardiac output (CO) exhibited an increasing trend, though without significance ( > 0.05). Mean arterial pressure (MAP) remained stable, although the GD group exhibited an upward trend post decompression ( = 0.1213).
Heartworm extraction and gastric decompression induced measurable cardiovascular improvements, with distinct recovery patterns. Non-invasive monitoring effectively captured cardiovascular changes, suggesting its utility as an adjunctive tool in clinical assessment.
胃扩张（GD）和心丝虫病（HW）会显著影响心血管功能，需要及时干预。本研究使用阻抗心动图（ICG）评估了这些情况下的血流动力学变化，ICG是一种用于实时监测的非侵入性技术。
在健康对照组、HW组和GD组的基线、干预期间和治疗后，使用ICG测量心脏参数。统计分析采用重复测量方差分析及事后比较，相对变化（%）量化血流动力学改善情况。
HW组（+14.71%，P = 0.0102）和GD组（+28.53%，P = 0.0336）治疗后心脏指数（CI）均显著增加。心输出量（CO）呈上升趋势，但无统计学意义（P>0.05）。平均动脉压（MAP）保持稳定，尽管GD组减压后呈上升趋势（P = 0.1213）。
心丝虫摘除和胃减压可引起可测量的心血管改善，且恢复模式不同。非侵入性监测有效地捕捉到了心血管变化，表明其可作为临床评估的辅助工具。
